Nintendo doesn't need to make new IP's, they need to manage their current ones

The question is not about how many they have, the question is how many of them fit current gamer's tastes. You know, those that can actually sell hardware...

Besides Splatoon, Nintendo hasn't really created a core game... a game that can appeal to MS and Sony fans.
That's the problem with Nintendo's current catalog: they lack the diversity or range of today's gaming genres.
